Tapio Behrndt

摘要:

研究了紧致黎曼流形上具有锥奇点的非齐次热方程Cauchy问题解的存在性和正则性。引入了具有离散渐近性的加权Hölder空间和索伯列夫空间,证明了当自由项位于具有离散渐近性的加权抛物Hölder空间或索伯列夫空间中时,非齐次热方程Cauchy问题解的存在性和极大正则性.这推广了Coriasco,Schrohe和Seiler(Thm. 7.2在数学Z. 244(2003),235- 269)。

英文摘要:

We study the existence and regularity of solutions to the Cauchy problem for the inhomogeneous heat equation on compact Riemannian manifolds with conical singularities. We introduce weighted Hölder and Sobolev spaces with discrete asymptotics and we prove existence and maximal regularity of solutions to the Cauchy problem for the inhomogeneous heat equation, when the free term lies in a weighted parabolic Hölder or Sobolev space with discrete asymptotics. This generalizes a result previously obtained by Coriasco, Schrohe, and Seiler (Thm. 7.2 in Math. Z. 244 (2003), 235--269) by different means.
